C Correct answer
Explanation

The CPU (Central Processing Unit) consists of three main components: Control Unit (CU), Arithmetic Logic Unit (ALU), and Memory Unit (registers/cache). The Control Unit directs operations, the ALU performs mathematical and logical operations, and the Memory Unit stores data temporarily during processing. The Output Unit is NOT part of the CPU - it is a separate component of the computer system that handles display or transmission of processed results to peripherals like monitors or printers.
